## Solution

Please try to re-install Azure CLI:

1. Go to **Control Panel > Uninstall a program** , uninstall **Microsoft Azure CLI**
2. Delete `C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2`
3. [Install the latest Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-windows?tabs=azure-cli) from scratch

## TODO

We should contact Windows MSI team to figure out why upgrading with MSI randomly fails.
